Enable & Using vGPU Passthrough

This gist is almost entirely not unlike Derek Seaman's awesome blog:

Proxmox VE 8: Windows 11 vGPU (VT-d) Passthrough with Intel Alder Lake

As such please refer to that for pictures, here i will capture the command lines I used as i sequence the commands a little differently so it makes more logic to me.

This gists assumes you are not running ZFS and are not passing any other PCIE devices (as both of these can require addtional steps - see Derek's blog for more info)

This gist assumes you are not running proxmox in UEFI Secure boot - if you are please refer entirely to dereks blog.

Use this as an example on how to start the virtual console without the need of Java Web Start or accessing it from the web interface.
You can use the user and password that you use for the web interface.

You need an old JRE... I used 1.7.0_80 from the Server JRE package, also I have tested successfully 1.7.0_79 with MacOS.
You don't need to install it, just extract it or copy the files in "jre" folder.

Open the viewer.jnlp file that you get by launching the virtual console from the web interface with a text editor.
Note the urls to the jar files. Download the main jar file avctKVM.jar and the libs for your operating system and architecture.
Extract the dlls (.so Linux, .jnilib MacOS) from the jar libs.
